I'll be teaching junior high/middle school aged kids (along with some younger ones) in a fun setting for the next few weeks. I've never worked with this age group before, so I'm not sure what comes across as too babyish for them. Any ideas for what to do when you need to get the attention of a busy/loud room? It's in the nature of the setting that the kids will be doing things noisily and independently and I'll need to round them up. I feel like the old "if you can hear me clap once" or rhythmic clap routines might be too young. Thoughts? Ideas? Thanks!
